Readonly values

By default all classes are immutable. If the GeneratorConfiguration option for immutability is disabled setters for all properties are generated. If single properties should be readonly the keyword readonly can be used.

{
    "$id": "person",
    "type": "object",
    "properties": {
        "name": {
            "type": "string",
            "readonly": true
        },
        "age": {
            "type": "integer"
        }
    }
}

Generated interface (with immutability disabled):

public function getName(): ?string;

public function setAge(?int $example): self;
public function getAge(): ?int;
